Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des verres de montre et plus précisément les verres de montre comprenant une loupe et résistant aux chocs.The present invention relates to the field of watch glasses and more specifically to watch glasses comprising a magnifying glass and resistant to shocks.

Arrière-plan technologiqueTechnology background

Il est connu de l'état de la technique des cadrans comprenant des billes. Toutefois, ces billes peuvent se mouvoir librement sur le cadran et lors d'activités sportives malheureusement, ces billes peuvent heurter le verre de montre et ainsi l'endommager ce qui nuit à l'aspect esthétique de la montre d'une part et dégrade la lisibilité des indications du cadran.Dials comprising balls are known from the state of the art. However, these balls can move freely on the dial and during sporting activities unfortunately, these balls can hit the watch glass and thus damage it, which harms the aesthetic appearance of the watch on the one hand and degrades the readability of dial indications.

On connait du document CH309970 une montre comprenant un verre de montre présentant un épaississement constituant une loupe, afin de permettre d'observer avec un certain grossissement une région du cadran.We know the document CH309970 a watch comprising a watch glass having a thickening constituting a magnifying glass, in order to allow a region of the dial to be observed with a certain magnification.

Le document US5805531 décrit à la figure 8 une montre avec une première chambre formée par un premier verre de montre avec une paroi latérale (19) contenant un premier mobile magnétique 18 et une deuxième chambre formée par un deuxième verre (9) et une paroi périphérique (7) dans lequel un deuxième mobile magnétique (5) se déplace uniquement dans cette chambre. Des aiguilles (1) placées sous le cadran (3) permettent de contrôler le mouvement des mobiles (5, 18). La paroi latérale ainsi que la paroi périphériques ne font pas parties du verre de montre.The document US5805531 described in Figure 8 a watch with a first chamber formed by a first watch glass with a side wall (19) containing a first magnetic mobile 18 and a second chamber formed by a second glass (9) and a peripheral wall (7) in which a second magnetic mobile (5) moves only in this chamber. Needles (1) placed under the dial (3) make it possible to control the movement of the mobiles (5, 18). The side wall and the peripheral wall are not part of the watch glass.

Résumé de l'inventionSummary of the invention

La présente invention se propose de résoudre totalement ou partiellement ces inconvénients grâce à une montre définie par la revendication 1 du brevet. Ledit au moins un premier élément mobile est confiné dans un espace restreint, ce qui limite son déplacement et évite que ledit au moins un premier élément mobile heurte un endroit du verre de montre d'une part et d'autre part, et que le choc dudit au moins un premier élément mobile sur le verre de montre soit trop important. Ainsi, ledit au moins un premier élément mobile peut heurter le verre de montre sans endommager le verre et sans nuire à l'aspect esthétique de la montre et donc dégrader la lisibilité des indications du cadran.The present invention proposes to totally or partially resolve these drawbacks thanks to a watch defined by claim 1 of the patent. Said at least one first movable element is confined in a restricted space, which limits its movement and prevents said at least one first movable element from hitting a place on the watch glass on the one hand and on the other hand, and that the shock said at least one first movable element on the watch glass is too important. Thus, said at least one first mobile element can strike the watch glass without damaging the glass and without harming the aesthetic appearance of the watch and therefore degrading the readability of the dial indications.

Le cadran de la montre selon l'invention comprenant un verre de montre, au moins un premier élément mobile configuré pour se déplacer librement dans ladite au moins une première chambre et au moins un deuxième élément mobile configuré pour se déplacer librement dans ladite au moins une deuxième chambre.The dial of the watch according to the invention comprising a watch glass, at least one first movable element configured to move freely in said at least one first chamber and at least one second movable element configured to move freely in said at least one second bedroom.

Grâce à cette disposition, les billes sont confiner dans un espace restreint, ce qui limite leurs déplacements et évite que les billes heurtent de manière simultanée un endroit du verre de montre d'une part et d'autre part, et que le choc d'une des billes sur le verre de montre soit trop important. Ainsi, ces billes peuvent heurter le verre de montre sans endommager le verre et sans nuire à l'aspect esthétique de la montre et donc dégrader la lisibilité des indications du cadran.Thanks to this arrangement, the balls are confined in a restricted space, which limits their movements and prevents the balls from simultaneously hitting a place on the watch glass on one side and the other, and that the shock of one of the balls on the watch glass is too large. Thus, these balls can strike the watch glass without damaging the glass and without harming the aesthetic appearance of the watch and therefore degrading the readability of the dial indications.

Ledit au moins un premier élément mobile et ledit au moins un deuxième élément mobile sont en matériau ferromagnétique.Said at least one first mobile element and said at least one second mobile element are made of ferromagnetic material.

Grâce à cette disposition, ledit au moins un premier élément mobile et ledit au moins un deuxième élément mobile peut être ou peuvent être aimanté(s).Thanks to this arrangement, said at least one first mobile element and said at least one second mobile element can be or can be magnetized.

La montre de l'invention comprend un cadran de montre, au moins une première aiguille aimantée située sous le cadran de montre et configurée pour déplacer ledit au moins un premier élément mobile à travers ledit cadran de montre et au moins une deuxième aiguille aimantée située sous le cadran de montre et configurée pour déplacer ledit au moins un deuxième élément mobile à travers ledit cadran de montre.The watch of the invention comprises a watch dial, at least one first magnetized hand located under the watch dial and configured to move said at least one first movable element through said watch dial and at least one second magnetized needle located under the watch face and configured to move said at least one second movable element through said watch face.

Grâce à cette disposition, les billes sont déplacées dans un espace restreint par l'intermédiaire des aiguilles aimantées de sorte à indiquer une information, ce qui limite leurs déplacements et évite que les billes heurtent de manière simultanée un endroit du verre de montre d'une part et d'autre part, et que le choc d'une des billes sur le verre de montre soit trop important. Ainsi, ces billes peuvent heurter le verre de montre sans endommager le verre et sans nuire à l'aspect esthétique de la montre et donc dégrader la lisibilité des indications du cadran.Thanks to this arrangement, the balls are moved in a restricted space via the magnetic needles so as to indicate information, which limits their movements and prevents the balls from simultaneously hitting a place on the watch glass of a on both sides, and the impact of one of the balls on the watch glass is too great. Thus, these balls can strike the watch glass without damaging the glass and without harming the aesthetic appearance of the watch and therefore degrading the readability of the dial indications.

Brève description de la figureBrief description of the figure

L'invention sera décrite ci-après de manière plus détaillée à l'aide du dessin annexé, donné à titre d'exemple nullement limitatif, dans lequel la figure unique représente une montre comprenant un cadran et un verre de montre selon un mode de réalisation.The invention will be described below in more detail using the appended drawing, given by way of non-limiting example, in which the single figure represents a watch comprising a dial and a watch glass according to one embodiment .

Description détaillée de l'inventionDetailed description of the invention

La figure unique représente un mode de réalisation de présente invention sous la forme d'un verre de montre 100 disposé sur une montre 300 et plus en particulièrement sur un cadran de montre 200 comprenant au moins une indication 201 comme par exemple l'heure ou la minute.The single figure represents an embodiment of the present invention in the form of a watch glass 100 placed on a watch 300 and more particularly on a watch dial 200 comprising at least one indication 201 such as for example the time or the minute.

Ledit verre de montre 100 de la présente invention comprend au moins une première chambre 110 dans laquelle au moins un premier élément mobile 210, typiquement une bille et de préférence en matériau ferromagnétique, peut se déplacer librement.Said watch glass 100 of the present invention comprises at least a first chamber 110 in which at least one first movable element 210, typically a ball and preferably made of ferromagnetic material, can move freely.

Par « se déplacer librement », il convient de comprendre qu'il n'existe aucun obstacle au déplacement dudit au moins un premier élément mobile 210. En effet, ladite au moins une première chambre 110 est comprise entre ledit cadran de montre 200 avec au moins une indication 201 et au moins une paroi supérieure 101 distante dudit cadran de montre 200, c'est-à-dire qu'ils sont séparés par un espace, et au moins une paroi latérale.By "move freely", it should be understood that there is no obstacle to the movement of said at least one first movable element 210. In fact, said at least one first chamber 110 is included between said watch dial 200 with at least one at least one indication 201 and at least one upper wall 101 distant from said watch dial 200, that is to say they are separated by a space, and at least one side wall.

Ladite au moins une paroi latérale 102 est comprise entre ladite au moins une paroi supérieure 101 et ledit cadran de montre 200 d'une part, et d'autre part ladite au moins une paroi latérale 102 entoure ladite au moins une première chambre 110, comme cela est représenté sur la figure unique, de sorte que ladite au moins une paroi supérieure 101 et ladite au moins une paroi latérale 102 forment ladite au moins une première chambre 110. Said at least one side wall 102 is included between said at least one upper wall 101 and said watch dial 200 on the one hand, and on the other hand said at least one side wall 102 surrounds said at least one first chamber 110, as this is shown in the single figure, so that said at least one upper wall 101 and said at least one side wall 102 form said at least one first chamber 110.

Comme cela peut être observé sur la figure unique, ladite au moins une paroi latérale 102 est plus épaisse que ladite au moins une paroi supérieure 101. En effet, l'épaisseur de ladite au moins une paroi supérieure 106 est plus faible que l'épaisseur de ladite au moins une paroi latérale 107. As can be observed in the single figure, said at least one side wall 102 is thicker than said at least one upper wall 101. Indeed, the thickness of said at least one wall upper 106 is weaker than the thickness of said at least one side wall 107.

Ainsi, la bille 201 ou les billes 201 sont confinées, autrement dit ledit au moins un premier élément mobile 210 est confiné dans un espace restreint, c'est-à-dire celui de ladite au moins une première chambre 110, ce qui limite sont déplacement et évite que ledit au moins un premier élément mobile 210 heurte un endroit du verre de montre 100 d'une part et d'autre part, et que le choc dudit au moins un premier élément mobile 210 sur le verre de montre 100 soit trop important.Thus, the ball 201 or balls 201 are confined, in other words said at least one first movable element 210 is confined in a restricted space, that is to say that of said at least one first chamber 110, which limits are movement and prevents said at least one first movable element 210 from hitting a place on the watch glass 100 on the one hand and on the other hand, and that the impact of said at least one first movable element 210 on the watch glass 100 is too important.

Ainsi, ces billes peuvent heurter le verre de montre 100 sans endommager le verre, puisque l'épaisseur de ladite au moins une paroi latérale 107 est assez importante pour dissiper l'énergie du choc dudit au moins un premier élément mobile 210, et cela ne nuit à l'aspect esthétique de la montre et donc ne peut dégrader la lisibilité des indications 201 du cadran.Thus, these balls can strike the watch glass 100 without damaging the glass, since the thickness of said at least one side wall 107 is large enough to dissipate the energy of the impact of said at least one first movable element 210, and this does not harms the aesthetic appearance of the watch and therefore cannot degrade the readability of the indications 201 on the dial.

Il est également possible de prévoir autre indication sur le dit cadran de montre et pour ce faire ledit verre de montre 100 peut comprendre au moins une deuxième chambre 120 configurée pour comprendre au moins un deuxième élément mobile 220, typiquement une bille et de préférence en matériau ferromagnétique, et au moins une paroi périphérique 103 configurée pour former ladite au moins une deuxième chambre 120. It is also possible to provide other indication on said watch dial and to do this said watch glass 100 can comprise at least one second chamber 120 configured to comprise at least one second movable element 220, typically a ball and preferably made of material ferromagnetic, and at least one peripheral wall 103 configured to form said at least one second chamber 120.

Ladite au moins une paroi périphérique 103 comprend également une épaisseur, mais comme ladite au moins une paroi périphérique 103 forme ladite au moins une deuxième chambre 120 et que cette dernière, c'est-à-dire ladite au moins une deuxième chambre 120 entoure ladite au moins une paroi latérale 102 et/ou ladite au moins une première chambre 110 et par conséquent ladite au moins une paroi périphérique 103 entoure ladite au moins une paroi latérale 102 et/ou ladite au moins une deuxième chambre 120, de sorte que ledit au moins un deuxième élément mobile 220 est relativement limité dans ses déplacements en comparaison avec ledit au moins un premier élément mobile 210, puisque ledit au moins un deuxième élément mobile 220 est confiné dans un espace compris entre ladite au moins une paroi latérale 102 et ladite au moins une paroi périphérique 103. Said at least one peripheral wall 103 also comprises a thickness, but as said at least one peripheral wall 103 forms said at least one second chamber 120 and the latter, that is to say said at least one second chamber 120 surrounds said at least one side wall 102 and/or said at least one first chamber 110 and consequently said at least one peripheral wall 103 surrounds said at least one side wall 102 and/or said at least one second chamber 120, so that said at least one least a second movable element 220 is relatively limited in its movements in comparison with said at at least one first movable element 210, since said at least one second movable element 220 is confined in a space between said at least one side wall 102 and said at least one peripheral wall 103.

Bien évidemment, selon la géométrie que peut arborer ledit cadran de montre 200, la forme la plus évidente pour ladite au moins une paroi périphérique 103 est la forme circulaire car elle permet de dévier aisément la trajectoire de ladite au moins un deuxième élément mobile 220, mais lorsque ledit cadran de montre 200 comprend des lignes droites, il est naturel de disposer ladite au moins une paroi latérale 102 à l'extérieur de ladite montre 300 afin d'éviter que ledit au moins un premier élément mobile 210 n'inflige un impact trop au verre de montre 200 de par la longueur de sa trajectoire.Obviously, depending on the geometry that said watch dial 200 can have, the most obvious shape for said at least one peripheral wall 103 is the circular shape because it makes it possible to easily deviate the trajectory of said at least one second movable element 220, but when said watch dial 200 comprises straight lines, it is natural to arrange said at least one side wall 102 outside of said watch 300 in order to prevent said at least one first movable element 210 from inflicting an impact too much to the watch glass 200 due to the length of its trajectory.

Un autre avantage qui peut être tiré de l'épaisseur de ladite au moins une paroi latérale 107 est l'effet loupe car étant plus épaisse que ladite au moins une paroi supérieure 101, l'épaisseur de ladite au moins une paroi latérale 107 permet d'obtenir de ladite au moins une indication 201 une image agrandie. Autrement dit, ladite au moins une paroi de séparation 102 a un effet loupe.Another advantage which can be drawn from the thickness of said at least one side wall 107 is the magnifying effect because being thicker than said at least one upper wall 101, the thickness of said at least one side wall 107 allows 'obtain an enlarged image from said at least one indication 201 . In other words, said at least one separation wall 102 has a magnifying effect.

Ces différents modes de réalisations peuvent être mis en oeuvre dans une montre 300 comprenant un cadran de montre 200, comme décrit précédemment.These different embodiments can be implemented in a watch 300 comprising a watch dial 200, as described previously.

Ladite montre 300 comprend au moins une première aiguille aimantée 310 située sous le cadran de montre 200 de sorte à déplacer ledit au moins un premier élément mobile 210 en matériau ferromagnétique à travers ledit cadran de montre 200 et au moins une deuxième aiguille aimantée 320 située aussi sous le cadran de montre 200 et pouvant également déplacer ledit au moins un deuxième élément mobile 220 en matériau ferromagnétique à travers ledit cadran de montre 200. Ainsi, les billes sont déplacées dans un espace restreint par l'intermédiaire des aiguilles aimantées de sorte à indiquer une information, comme par exemple l'heure ou les minutes, ce qui limite leurs déplacements et évite que les billes heurtent de manière simultanée un endroit du verre de montre 100 d'une part et d'autre part, et que le choc d'une des billes sur le verre de montre 100 soit trop important. Ainsi, ces billes peuvent heurter le verre de montre 100 sans endommager le verre et sans nuire à l'aspect esthétique de la montre et donc dégrader la lisibilité des indications 201 du cadran.Said watch 300 comprises at least one first magnetized needle 310 located under the watch dial 200 so as to move said at least one first movable element 210 made of ferromagnetic material through said watch dial 200 and at least one second magnetized needle 320 also located under the watch dial 200 and also being able to move said at least one second movable element 220 made of ferromagnetic material through said watch dial 200. Thus, the balls are moved in a restricted space via the magnetized needles so as to indicate information, such as the hour or the minutes, which limits their movements and prevents the balls from simultaneously hitting a place on the watch glass 100 on one hand and the other, and from the impact of one of the balls on the glass 100 is too high. Thus, these balls can strike the watch glass 100 without damaging the glass and without harming the aesthetic appearance of the watch and therefore degrading the readability of the indications 201 on the dial.
